In this subsection, the Lyapunov controller proposed in [1]} and the Backstepping controller developed in [2]} are used for comparative analysis with the proposed controller.
All simulations are performed on nonlinear PDE systems.
To check the robustness of the system (REF )-() under different controllers, we consider the two situations where a Gaussian noise is added to parameter \(\alpha \)  and mismatched delay value, respectively.
